yii2：正确的方法来抛出新的异常 [英] yii2: Proper way to throw new exception

问题描述

只是为了测试，我在我的模型中添加了这个代码，同时设置了debug = true和false。

  if（$包装日期< 1）
 {
 throw new \yii\base\Exception（package days不能小于1）; 
} 
  

现在Yii调试是真的：我得到

异常 - yii\base\Exception
包装日不能小于1

但是当我将调试设置为false
我得到
异常
发生内部服务器错误。

Web服务器正在处理您的请求时发生上述错误。

我想要的是替换发生内部服务器错误。
with
包裹天不能小于1 当 debug = false

谢谢。

解决方案

你应该简单地抛出一个 UserException ：

UserException是异常的基类旨在向最终用户显示。

Just for testing I have added this code in my model while setting the debug = true and false.

if($packagedays < 1)
     {
      throw new \yii\base\Exception( "package days cannot be less than 1" );
     }

Now when Yii debug is true: I am getting

Exception – yii\base\Exception package days cannot be less than 1

But when I am setting the debug to false I am getting Exception An internal server error occurred.

The above error occurred while the Web server was processing your request.

What I want is to replace the An internal server error occurred. with package days cannot be less than 1 when debug=false

What I am missing here?

Thanks.

解决方案

You should simply throw a UserException :

UserException is the base class for exceptions that are meant to be shown to end users.
